27.4.3.18 The memory_by_user_by_current_bytes and x$memory_by_user_by_current_bytes Views

These views summarize memory use, grouped by user. By default, rows are sorted by descending amount of memory used.

The memory_by_user_by_current_bytes and x$memory_by_user_by_current_bytes views have these columns:

  • user

    The client user name. Rows for which the USER column in the underlying Performance Schema table is NULL are assumed to be for background threads and are reported with a host name of background.

  • current_count_used

    The current number of allocated memory blocks that have not been freed yet for the user.

  • current_allocated

    The current number of allocated bytes that have not been freed yet for the user.

  • current_avg_alloc

    The current number of allocated bytes per memory block for the user.

  • current_max_alloc

    The largest single current memory allocation in bytes for the user.

  • total_allocated

    The total memory allocation in bytes for the user.
